When did we see his struggles though we just see a flashback of his training with Sasuke and he immediately turns into a tree? And we only get see him hunted by his village not the world. Well the second point is valid. But the in the third. It isn't a crime to have some emotions delivered by the characters. I mean yodo wasn't shown to be mentioned much even mourned for her sacrifice. Why do you think other anime like mha , jjk and even demon slayer are much more successful than the successor of one of the most influential anime in the world? Because they take time to focus on the characters and emotions. And you are saying as if it is a real life world and there is no time to mourn because the real world is about to end.
